Minnesota government shutdown: Not over yet

NEW YORK (CNNMoney) -- Four days after Minnesota leaders said they reached a budget deal, the state government remains shut down.

Though leaders said last Thursday that they hoped to swiftly end the longest state shutdown in recent history, they are still hammering out the details of the agreement. Several Republican lawmakers are balking at some of the deal's provisions, according to local press reports.

On Sunday evening, Governor Mark Dayton and the Republican legislative leaders issued a joint statement saying that state officials worked around the clock for three days. But it did not set a date when Dayton would call lawmakers to the Capitol to vote on a deal.

"Considerable progress has been made," the statement said. "A special session will be called as soon as our work is completed, and all bills have been reviewed and agreed upon."

The negotiations are continuing Monday.

"We had hoped to perhaps get it done by today, but it is difficult work and [there are] many details to get through," said Katharine Tinucci, Dayton's press secretary.

Last week, it looked like the shutdown, which began July 1, would end rather quickly after Dayton dropped his demand to raise taxes on the wealthy.

Instead, the governor agreed to plug the remaining $1.4 billion budget gap by delaying state aid to schools and issuing bonds against future tobacco settlement payments. In turn, he demanded Republican lawmakers set aside various policy issues and drop their demand to cut 15% of the staff in all state agencies.
